What I did was to NOT peel off the backing but instead used double sided foam tape strips to attach the lightstrip where I wanted it. When I moved recently, I just peeled the lightstrip away from the foam strips and used a fresh set of double sided foam tape strips to adhere the lightstrip in place in my new home. If you never peel off the backing on the tape on the lightstrip itself, this should allow you to reposition the lightstrip as often as you like with impunity.

Yes, LED strips can be connected using small plastic connectors specifically for LEDs. You cannot link more than 5 meters of LED strips in one go. If you do, then you will need to add an extra power supply at the 5m point.

Yes. You can dim the strips with a supported app. If you try the "Hue Lights" app it will let you change every attribute of Light Strips: Hue, Saturation, Brightness, Alert, and Colorloop. The LightStrip values can be set with sliders, steppers, or direct input. You can also pick from Favorites at various color and brightness levels or add the LightStrips to your scenes.

There are spots every so often where you can cut the strip shorter. Many similar light strips have the ability to add additional strips to extend the length. While Philips doesn't seem to sell a connector to do this easily I'm sure you could do it by soldering tiny jumper wires to the contacts on either side of where you cut it. The only question then would be how many additional LEDs can the power source power.

You will need to download a third-party application to control the Hue lights from your MacBook Pro. There are a lot more apps than applications available. Philips recently updated their developer's library to work with both apps and applications, so there will probably be more third-party applications coming in 2014.

If this is to be used as undercabinet lighting in a kitchen remodel/build can these be hardwired into the electrical? If not, can you shorten the power cord part (that has no lights on it) since it is so long?

The power cable is a fixed length as well. However, the light strip itself can be cut to length and the power supply can be mounted under a cabinet....so its certainly possible to hide fairly well. You could also have an outlet added underneath the cabinets so no wire shows at all.

Yes, it does require Hue Bridge. As stated under the Highlights section of the product page: "Requires a Philips Hue bridge, which is available from the Apple Online Store as part of the Philips Hue Connected Bulb - Starter Pack."

People often through about the "16 million" figure, even in marketing literature. However this comes from number of distinct addressable colours in RGB with 8 bits a primary colour.

2^(3*8) = 2^24 = 16,777,216

Philips Hue technology does not use RGB rather a subspace of CIE. There are many colours in RGB space which cannot be produced by Philips Hue bulbs. There are also some colours which can be represented which do not map well to RGB. I'm sure there are a lot of colours, but how many?

The LightStrips use the hue/saturation color mode for producing their colors. To change colors the app sends commands to the SmartBridge. You can send 65,536 hue values and 256 saturation values: 65,536*256 = 16,777,216.

In reality, it is very hard to distinguish hue or saturation values when they are very close. You can also dim the bulbs in 256 distinct levels. The current SmartBridge maps any 255 values to 254, so saturation and brightness really support 255 levels. Again it is hard to see any difference for values that are very close.

I'm getting a boat and it would be really nice to use these to light it up beautifully inside. Boat-based color-changing LEDs are prohibitively expensive and don't seem to be as flexible in their operation.

If you use a power inverter, you should be able to use the lightstrips with a 12 volt power source. However, none if the Hue lights (Lightstrips included) are rated for outdoor use. Thus, you'd have to use them inside the cabin, if you have one, not outside.

The problem is that I noticed in some unboxing videos that there's an on/off switch to control the light on/off. I want to control on/off remotely through the iPhone app (or the Logitech Ultimate which controls Hue light bulbs).

Yes, it is possible to turn these lightstrips on and off exclusively using the Hue app on your iPhone. This is exactly how I use mine. It plugs directly into an AC outlet and is controlled by the app (on/off, color, brightness).

The control box and power supply should be kept away from direct water sprays or high humidity. The LightStrip can be placed in humid areas, avoiding direct water sprays.
